Larger counter. It's not a FAT-based filesystem either, so the
directory structures are free to grow as needed.

In a word, amazed. I know many who can't see the flicker
(and are amazed I can identify the scan rate), but *all*
report better results after iI fix their display. I simply
cannot look at a 60Hz monitor. At work many people have
"server" systems as their office systems. Gag!

Yep.

Nope. Modern monitors have a very short phosphor to
eliminate those "trails". If you are really interested take
a decent 35mm camera of a display in natural light. It's
easy to deduce the phosphor decay rate. It's quick.

Apparently! I've gone there and done that. No way is
having a virtual desktop larger than real beneficial to me.
WHen I set up my desktop everything is exactly whare I need
it for that function. Again, dual displays are a big help.
My secondary display is normally used for one window (lately
my simulation "wave" window, but my synthesis schematics
also end up there).

I find that inconsistant with my experience. My WinWindows
scroll quite nicely. Though I am talkking about high end
hardware, bought by my boss because *I* am expensive. ;-)
..ok the software on my system has a huge price too.

Eight years ago was "at home", on a 15" display. I'm a tad
older than you and can tell you that you're looking throung
very filtered glasses. Do I have a flatscreen at home?
Nope, too cheap. ;-) I have a 19" display here though (but
don't sleep in front of it ;-).

Well, I did the 4.77MHz thing 20 years ago and gave it up in
the mid 80s (still have it to aggravate the Mrs.). THis
system (mostly Inet and simple text stuff) is a K6-III 400
on a Tyan 1498C2 (2MB cache). My work laptop is a 850MHz
Piii (with a damned fine LCD display ;-).

Not good enough. I need access to all windows (maybe 10-12)
in an application simultaneously. My simulator is a bitch
for needing open and usable windows. Displaying 20-30
waveforms takes up the other screen.

Maybe, but when all windows are needed consistantly, large
desktops are a real productivity enhancement. I'll swap my
primary display between the simulator and synthesis tool,
but I'll (usually) keep the waveforms on the secondary
display.

Interrupts are bad. When I'm thinking I throw the
headphones on and do a tune or two (likely not your style of
music ;-). Many studies have shown that it takes 15 minutes
to get into a deep concentration state and only one phone
call to lose it. ...then we get into the performance of the
system. Dean, that's your cue. ;-)

Get rid of the "=" signs in the lines above. They'll break the process,
since the fields are supposed to be separated by spaces (or possible tabs

A CRT is *never* perfect. It is degredated by design,
alignment, and environmental errors. An LCD is as perfect
as the eye can ever see. A CRT can never approach the
precision of an LCD display.

If you're talking about the $1900 display (F500R, I believe
it's called), then absolutely. At half the cost of a
top-end ThinkPad (actually .75% today), yes, I'll take the
LCD. The specs on even that monster don't look a lot better
than a P260 and I'd take my LCD over that monster any day
(though may get a P260 for my secondary). I wouldn't trade
the LCD for a 21" monitor, of any make. It's that good. I
wouldn't have believed it (I was into behemouth monitors
too), but after working on it for three months, I'm a
believer!

I was there too. My second phone line cost me $50 a month.
Add in two ISPs at $43/month and a $40 cable modem looks
very right. As soon as they woruld take my order... I'm
outside the range of DSL, so our stinkin' cable company gets
a check for $100, and change, a month (mother got digital

The latter is far more likely.

I have hardware rotting around here that I was going to do a
firewall/router/server with. Nah, I have other things to
do. The LinkSys box was much easier! I really don't want to
learn about the guts of the Inet. I have more profitable
uses for the limited time and energy I can devote to
learning.

I wonder if anyone can give me a hint as to how to diagnose and/or fix
my problem. My Red Hat 7 system reboots spontaneously from time to time,
and fsck runs because the filesystem was not cleanly unmounted. There
are usually fsck errors. It is as if someone pressed the reset switch on
the PC. It always happens on some sort of user input: a mouse click,
usually, or a page up keystroke.
I have run memtest86 for hours. I have tried different X servers (4.0.1,
4.0.2 and 3.3.6), different keyboards, different mice (PS/2 and USB) and
still see this problem. It occurs when using various X apps (Opera,
Applix, Netscape, Gimp), regardless of X toolkits (Qt, Gtk, Motif). I
have installed various Red Hat updates (glibc, kernel) and different
versions of KDE, to no avail.
Hardware: BC133KT motherboard, Duron 700 CPU, 128MB Ram, ATI XPert98 PCI
video, 2 Netgear FA310TX PCI network adaptors, one internal ISA
modem. Software: Red Hat 7 with a whole bunch of fixes, KDE 2.1, XFree86
4.0.2 (from Raw Hide) and 3.3.6 Mach64 X server. I'm just about out of
ideas. Anyone?
Thanks in advance,

That is almost certainly a hardware problem. Changing software is
not going to have any effect at all.
You can try things like reseating all connections to the motherboard
(such as IDE cables, etc.) and reseating the memory cards and the
cpu. If all else fails, get a new motherboard.

Greetings from Bullwinkle:
I think you need the SVGA driver. Also with XFree 3.3.6
I needed to add some options in the Section "Device" part of
the XF86Config file, "no_accel" and no_bitblt". Different
video cards with this chipset may need different options.
For an explaination of the various options, see http://www.xfree86.org/
For instance;
try http://www.xfree.org/3.3.6/SiS3.html#3 for version 3.3.6
and http://www.xfree.org/4.0.2/SiS2.html#2 for version 4.0.2
I am not sure you can get full functionality from this chipset
with XFree, but more than likely you can get a fairly good display.

You might be looking for the wrong item.
IEE 1394 is a bus, and the only reason I can think of you would need the
tech details would be to write a 1394 driver. That is, a driver for a
generic i1394 bus -- not a device connected to i1394.
If I'm wrong, the full specs are available to IEEE members (not cheap for a
hobbiest) on the IEEE Standards web site:
http://standards.ieee.org/catalog/olis/index.html
* * *
Usually the drive on the backend of an i1394 storage chain is either SCSI
or IDE (of ATAPI, if a CD-ROM) wrapped up in a converter. You need the
command set for the device. Try generic SCSI commands and see what you
get. Odds are that'll work.

Hi all,
Is anyone familiar with this motherboard? I have just received a PC at work
with this board, and I have several problems configuring Linux. The video
card behaves strangely (it is an on-board Intel 82815, for which XFree
assigns the Intel810 driver), and sound cannot be configured at all (I think
it is an on-board ADI 1885 SoundMax).
Thanks, Elad
